S103. Determine the display area that can be used for display in the undamaged area according to the position of the cursor bright spot and the coverage area of the cursor bright spot;

S104. Adjust the image to be displayed according to the size of the display area, and display the adjusted image in the display area.

The screen display method provided by the embodiment of the present application triggers a detection program to display a cursor bright spot on the screen when the screen includes a damaged area and an undamaged area (that is, when the screen is damaged). By determining the position of the cursor bright spot and adjusting The size of the area covered by the cursor bright spot determines the display area that can be used for display in the undamaged area, adjusts the image to be displayed according to the size of the display area, and displays the adjusted image in the display area, thereby making full use of the partially damaged screen , it will not be completely scrapped, and it can quickly adjust the display screen and interact with the interface, saving time without increasing the hardware cost. It is compatible with already launched products and is conducive to promotion.

Specifically, as shown in Figure 2, the screen 102 includes a damaged area 105 and an undamaged area. The whole machine 101 is provided with a plurality of buttons 106. When the damaged area 105 appears on the screen 102, the user presses the preset button. After receiving the user's pressing signal, the detection program is triggered to display the cursor bright spot 104 on the screen 102; during specific implementation, the preset button can be a combination of two buttons 106 or more buttons 106 set on the whole machine 101. When triggering the detection program, the combination of multiple buttons 106 can avoid the conflict of existing button functions. Of course, in order to trigger the detection program, the existing buttons 106 on the whole machine 101 may not be used, but may be added separately on the whole machine 101 A button, using the added button to trigger the detection program.

In an optional embodiment, determining the position of the cursor bright spot according to the center position of the undamaged area includes: scanning the cursor bright spot point by point along the row where the starting position is located, and after the current row scan is completed, the cursor bright spot Scan the next line point by point; when the cursor bright spot scans to the center of the undamaged area, stop scanning and record the current coordinates of the cursor bright spot to Determine the position of the cursor highlight spot.

Scan point by point at a constant speed along the row of the starting position; when the cursor bright spot scans to the center of the undamaged area, stop scanning, including: when the cursor bright spot scans to the center of the undamaged area, the default button receives Operation signal triggers the scan end program to stop scanning.

In actual use, there is randomness in the location of screen damage, which may block the starting position of the cursor's bright spot. Therefore, no confirmation operation is required when the cursor's bright spot appears and starts to move. After the detection program is triggered, the cursor's bright spot appears on the screen. The other areas are all black, as shown in Figure 2. When the preset button receives the user's pressing signal, the scanning program is triggered, and the cursor bright spot 104 scans along the cursor bright spot scanning trajectory line 103. Specifically, the upper left corner of the screen Taking the starting point as an example, the cursor bright spot 104 scans point by point from left to right along the line where the starting position is located at a constant speed (set the speed according to the actual situation). After scanning to the far right, it automatically jumps to the next line and repeats the scan. action, after scanning the last line, it will jump to the first line and repeat the scanning action. During the repetitive scanning process, observe the center position 108 of the undamaged area. When the cursor bright spot 104 scans to the center position 108 of the undamaged area, Press the preset button, and after receiving the user's pressing signal, the preset button triggers the scanning end program, stops scanning, and the cursor bright spot 104 stops at the center position 108 of the undamaged area.

In the embodiment of this application, when the preset button is pressed to trigger the scanning program, the cursor positioning program is also triggered. The cursor bright spot automatically scans from the starting position at a constant speed. The program set in the screen display device will automatically record the current cursor bright spot. Coordinates, when the preset button is pressed again, the scan end program is triggered, and the cursor bright spot stops scanning. Only the coordinates of the last cursor bright spot are retained. The last coordinate of the cursor bright spot is the determined position of the cursor bright spot. Since part of the screen is damaged and cannot be displayed normally, the operating steps must be reduced. In the embodiment of the present application, a preset button click is used (that is, the user presses a preset button) to trigger the scanning program and the scanning end process, which does not involve too much Input does not involve too much confirmation, which can reduce operation steps; since clicking may miss the operation time window, the use of repeated cyclic scanning of the cursor bright spot can provide multiple operation opportunities.

In an optional embodiment, adjusting the size of the cursor's bright spot coverage area based on the position of the cursor's bright spot includes: taking the position of the cursor's bright spot as the center, increasing the size of the cursor's bright spot coverage area to no more than Beyond the boundary of the undamaged area; record the position information of the current cursor bright spot coverage area to complete the size adjustment of the cursor bright spot coverage area.

Specifically, taking the position of the cursor's bright spot as the center, increasing the size of the cursor's bright spot coverage area to not exceed the boundary of the undamaged area, including: preset buttons to receive operating signals and trigger the adjustment program; taking the position of the cursor's bright spot as Center, increase the size of the area covered by the cursor's bright spot at a set rate until it does not exceed the boundary of the undamaged area; re-center the position of the cursor's bright spot, and increase the size of the area covered by the cursor's bright spot at a set rate until it does not exceed the boundary of the undamaged area. The boundary of the undamaged area will stop increasing the size of the cursor bright spot coverage area until the preset button receives the operation signal again.

In specific implementation, as shown in Figure 2, when the cursor bright spot 104 stops scanning, the cursor bright spot 104 stops at the unbroken area. The center position 108 of the damaged area, the cursor bright spot 104 is centered on the center position 108 of the undamaged area, and increases at a set rate. The increase shape can be any shape, for example, it can increase in a circle. When the cursor bright spot coverage area is about to exceed the display range of the screen, press the preset button to stop increasing the size of the cursor bright spot coverage area to complete the adjustment of the cursor bright spot 104. At this time, the size of the cursor bright spot coverage area is as shown in the figure The cursor bright spot coverage area 107 in 2; of course, after the cursor bright spot 104 completes an adjustment, if the preset button is not pressed in time, the cursor bright spot 104 can be restored to the initial size and initial position, and can be set again. The speed increases, and in this way, the adjustment of the cursor bright spot 104 can be repeated multiple times.

The shape of the cursor bright spot 104 when it increases in the embodiment of the present application is a circle as an example. When the preset button is pressed to trigger the adjustment process, the current radius of the cursor bright spot 104 is recorded after each adjustment. After pressing the preset button again to complete the adjustment of the cursor bright spot 104, only the last radius value is retained. In the embodiment of the present application, a preset button click is used to trigger the adjustment program and the adjustment end program, which does not involve too much input or confirmation, and can reduce operating steps; due to the click method, the operation time window may be missed. , so the method of repeatedly increasing the cursor's bright spot can provide multiple operation opportunities.
